A generally indicates any suitable base frame or member provided for example with the anti-frictional and noise deadening studs or supports A Mounted on such base member is any suitable motor means herein shown as the motor 18 from Which projects the motor shaft B on which is the driving pulley B adapted to engage and drive the belt 18 herein shown as of triangular cross-section to engage the inclined faced channel ll on the pulley B C is a knife supporting sleeve mounted upon the base A and. including the shield port'on C lit Will be understood that the shield portion is continuous with or extends to the motor housing F5 and forms part of the general upwardly projecting housing or frame member C Mounted within the sleeve portion C is an inner sleeve D in which are mounted the ball bearing tracks l) to support the balls D opposed to the inner tracks D on the knife s raft D are looking nuts whereby to secure the lrnife shaft and roller bearing assembly together, the shaft it)" being enlarged as at D to engage the inner forward ball track D D is a channel pulleymounted on the shaft D adapted to receive about it the belt B.

E is a knife disc proper secured to the shaft assembly for example by the screw l5 and additionally secured to the pulley l) for example by the screws Ff. The knife disc is shown. as convex and is peripherally cut-away or recessed on its hollow face, as at E to leave a peripheral portion projecting somewhat forwardly from the face of the knife, the inner face of which is preferably, but not necessarily cupped.

l he sleeve t is apertured as at G, the aperture passing partially through the cylindrical interior of the sleeve. Mounted in such aperture is the locking pin G cut away as at t to permit the passage of the inner sleeve l).

lllounted on the forward face of the frame member (7 is the fixed guard plate H which may be of any suitable material. At its left edge as shown in Figure 3, it is arcuately cut away as at ll the arcuate portion pens trating or seating closely Mthin the peripheral channel F f the lm the lrnife being ,grhtly tint" .t tal plane from per in a horizon y to the plate the edge or pendicu'nrit as shown in Fi ggure 2 to e E the axis of flu lift

till) lift the'knife forward into the in such figure, generally in t guard plate H.

position shown e plane of the J is a frame or housing member upward- 'which is the worm J Such shaft is controlled by the external handle J provided with indicating symbols as at J aligned with the opposed pointing member J Pivoted to the vertical rock shafts J J" within the housing J are the levers or pairs of levers K, K, at the outer end -of each pair of which are pivoted the blocks or strips K, to which 'are secured any suitable gauge plate K the surface of which may-be slightlyconvex or bowed, to conform to the cutting edge of the knife E since the active cutting portion of the knife, due to the angle at which it is set, is not in a vertical plane but is slightly bowed forward. The ri ht edgeof said gauge plate K as shown in 1gure 3, may be arcuately formed, as at K, generally concentrically with the arcuate portion Hiof the fixed guard plate. The distance separating the opposed edges is, as

shown in Figure 2, sufficient to permit the penetration therebetween of the peripheral port-ion'E of the knife E.

Secured to the rock shaft J is a segment worm gear K which meshes with and is driven by the worm J A tension spring K is secured at one end to a lug K on the frame J and at its opposite end to one of the pivoted blocks or strips K This spring serves to hold the teeth in the segment K in close contact with the opposed teeth of the worm J Coiled around the upper part of the rock shaft J is a heavy spring K ,.which is held under compression against the under side of one of the bearing lugs K and by the collar'K which is secured to the rock shaft J. The resulting friction acts as a brake, and tends to hold the gauge plate K in any position in which it may be set by the operation of the handle J v The support of the auge plate by means of the parallel links K not only provides for the maintenance of the exposed face of the gauge plate in uniform angular relation to the forward face of the guard plate, and relative to the line of movement of the can riage 0, below described, but also makes possible the gradual widening of the throat between the active edge of the cutter and the forward edge of the gauge plate as that throat is deepened to provide for thicker slices, thereby providing the necessary amount of clearance for the thicker slices. It will be readily understood that various well-known mechanical mountings for the gauge plate, by which uniform angular relation throughout adjustment may be maintained, and by which the desired widening of the throat is attained as the throat is deepened, will readily suggest themselves to the avera e mechanic.

It will be understood that when the gauge plate is advanced to the position shown in full line in Figure 2 itmasks the cuttin edge of the knife and is in what may call neutral position. An operator can then clean the face of the gauge plate and, in order to prevent possibility of the gauge plate slipping back and exposing the ed e of the knife, I provide locking means for the handle or knob J, as shown particularly in Figures 6 and 7. Referring to such figures J is a recess in the frame, in which is mounted the lockin ball J normally outwardly thrust b the spring J. The peripheral flange of the knob J 3 is slotted or indented as at J in such fashion, or at such a location that, when the auge plate is in neutral sition, the slot 15 overlies the aperture and receive the lock ball G". The locking effect is sufiicient to prevent unintended rotation of the knob J for example by unintended contact of the arm or body.

The gauge plate K is illustrated as adjustable toward and away from the edge of the knife in order to conform and allow for wear of the knife or substitution of knives of somewhat differing diameter. I illustrate as means of adjustment; the slots K in the plate through which pass screws or other suitable securing means K whereby the gauge plate may be laterally moved in relation to its rear supporting plate K to which are directly attached the strips or blocks K K is a clamping washer, as shown in Figures 13 and 14.

Preferably I make the slots I of. such size in relation to the stems of the screws I as to permit also vertical adjustment of the gauge plate and tilting of the guage plate from the horizontal.

K is any suitable top or lid member extending from end to end of the slicing machine and adapted to be secured for example by the screws to the housing J and to the housing or. frame member C.

L is any suitable receiving plate for receiving the material sliced by the knife and L is any suitable control switch for controlling the current to the motor of the motor housing B.

The ends of the track are enclosed by the sheathes M apertured to permit the penetration of the bolts or screws M headed as at M and upwardly extending through the base A, the support members M the sheathes M and into the ends of the track lvf.

Z is a lock nut and Z a ledge or flange on the pin X whereby the pins, when adjusted, may be locked in position.

\ It will be realized that whereas have illustrated and described a practical and operative device nevertheless many changes might be made without departing from the spirit of my invention, and it therefore wish my drawings and description to be taken .as in a broad sense illustrative and diagrammatic rather than as limiting me to my precise showing.

The use and operation of my invention are' as follows:

I provide a generally vertical, normally fixed. guard plate. arcuatel cut away to permit the pentration or t e exposure of the edge of the rotary ltnife, about a relatively restricted arc. The plane of. the knife is tilted in order to bringthe exposed edge generally into the plane of or close to the plane of the forward face of the guard. plate; The knife is hollowed or sunk in order to permit its peripheral portion E to extend forwardly beyond the body of the knife and beyond the forward face of the guard plate. Generally aligned with the guard plate H is the adjustable gauge plate K", controlled by the worm J which in turn is controlled by rotation of the handle or lrnobd The gauge plate may, if delOO sired, be slightly bowed to conform to the curvature of the exposed knife edge due to the inclination of the axis of the knife or the tilting of the plane of the knife'out of parallelism with the path of movement of the carriage.

An important characteristic of my device is the tilting of the knife guard plate H and the gauge plate ii in such fashion that their opposed edges more closely approach the carriage or the path of'the carriage than do the other portions of their surface. This is illustrated in Figure 2 and is diagrammatically accentuated in Figure 10. lhis has for effect to permit a very close adjustment or approaching of gauge'plate and guard plate and knife edge to the path of the carriage and to the forward edge of the carriage along the area which determines the thickness of the slice, namely where the riage, and to maintain all parts of the plate equi-distant from the carriage path, and this limits the closeness of adjustment of knife edge to carriage. Tilting the plates, as herein. shown, permits a very close adjustment of their forwardly extended edges, an adjustment which can be made regardless of minor distortions of the rest of the plate. In particular, the gauge plate, when slightly tilted, can be adjusted, when in neutral position, so that its edge masks the cutting edge of the knife, thus making it safe for the operator to clean or wipe the forward 'fa-ce ofthe gauge plate. IVhere it is attempted to adjust the entire plate in parallelism, it often happens that it is impossible to thrust the entire plate so far forward as completely to mask the cutting edge when the plate is in neutral position.

The gauge plate is adjustable, in response torotation of the worm, and moves toward or away from the path of the carriage, the angular relation at which it is set being constantly maintained. a

The material to be cut is placed upon the carriage O, and is moved, for the cutting excursion, from left to right as shown in Figures 2 and 3. The thickness of the slice is determined by the position of the right edge of the gauge plate K in relation to the exposed cutting edge of the knife, the slice passing through the aperture between knife and gauge plate anddropping upon the receiving plate L, from which it may be manually removed. lVith the gauge plate supported as herein shown, as the plate is moved backwardly from the cutting plane, in order to increase the thickness of the slice, the arcuate edge of the gauge plate also draws laterally away from the cutting edge, so that the throat between gauge plate is both deepened and widened.

As shown in Figure 2, the guard plate l-l may be adjusted toward and away from the knife, for example by means of rotation of the threaded stud bolt Q, screws to the lugs Q on the frame C and secured by the screws Q threaded into the stud bolt Q. Thus the guard plate can be set at any desired angle but it is preferably, as above stated, tilted back with its left edge, as shown in Figure 2, most closely approaching the line of movementof the carriage.

In the form of Figure 2, the carriage is provided with outwardly projecting guiding pins or tracks P along which slide the members P associated with the handle P and the meat face plate P. The employment of a pair of positive guiding pins maintains the face plate at a constant angle in relation to the front of the carrier and the path of movement of the carrier. This angle may be adjusted by means of the screws P and the lock nuts P, it being possible to tilt one or the other side of the face plate forwardly or rearwardly, in order to obtain the desired parallelism.

In the form of Figures 9 and 10 the face plate carries its own pins or tracks X which penetrate apertures X in the carriage O. In the variant form I show the tracks or pins X as laterally adjustable in order to compensate for possible variations between centers of the apertures X, due to warping or misshaping during the baking of the enamel upon the carriage, when an enamel coating is applied to the metal of which it is composed. The face plate P is therein shown as fixed in relation to the supporting pins X, such pins being adjustable in relation to the handle X Thus not only is angular relation of the plate permitted, but a very substantial range of adjustment toward and away from the cutting plane. This permits close adjustment and variation of the maximum approach of face plate to cutting plane.

It is also important that the forward face of the carrier itself be adjusted to parallelism with the cutting plane and I therefore provide the adjustment shown forexample in F igu're 4, whereby it is possible to tiltthe carrier about the circular track M through adjustment of the opposed screws 0 0 as shown in Figure 4.

The gauge plate is adjusted toward and away from the knife E. I have illustrated the slots K and the screws K and they are preferably of such size in relation to each other as to permit the gauge plate also to be adjusted verticallly or to be tilted from the horizontal. I am thereby enabled to adjust the gauge plate and the arcuate portion thereof not only to different diameters and sizes of knife and to the same knife, as it wears down. The vertical and tilting adjustment permits the operator to adjust the arcuate 'portion of the gauge plate very accurately in relation to the center of rotation of the knife.

Referring to Figures 11 and 12 I have illustrated the pin X as provided with an eccentric stem Z penetrating and snugly fitting the aperture Z in the handle member X The pins X may be rotated about the center of rotation of the eccentric portion Z until they conform to the opposed apertures X in the frame. \Vhen so adj usted they are fixed in position by the lock nut Z I claim:
